Large early morning blaze at warehouse under investigation, Sacramento Fire says

A large, four-alarm structure fire at a mostly unoccupied warehouse building on North 16th Street was extinguished early Thursday morning, Sacramento Fire Department officials said.

About 100 firefighters responded to a fire that had broken out about 3 a.m. on North 16th Street near North B Street, Fire Department spokesman Capt. Keith Wade said. It was fully extinguished by about 5:45 a.m.

The fire started at a building owned by General Produce Co. The U-shaped building is about the size of a city block, and only about one-quarter of it was burned, Wade said.

That section of the building has been vacant for about six months, Wade said, though it had some flammable materials remaining inside.
